OSM Public Transport schemes support for buses and trams is not implemented yet, and it's not an easy task. Any volunteers to lead the development are welcome!

Here is the entry point to the current subways validator with wiki links at the bottom: https://cdn.organicmaps.app/subway/

Is there any corporate funding for this work?

The original subway validator was created by the original (before the second sale) maps.me team. Now it is supported voluntarily.
